objective-c - 禁用两指捏住UIScrollView中的平移

我想停止滚动后，发现第二次触摸和处理触摸与我自己的捏手势。
我在滚动视图中尝试过：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    if(event.allTouches.count > 2)self.panGestureRecognizer.enabled = NO;
}
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
    if(event.allTouches.count > 2)self.panGestureRecognizer.enabled = YES;
}

但没用。
试试这个：
scroll.panGestureRecognizer.maximumNumberOfTouches = 1;
但什么都没有

最佳答案

我找到了解决办法。我重新定义了uiscrollview，并添加：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer
{
    return YES;
}

以及禁用/启用平移手势：

if(pinch.state == UIGestureRecognizerStateBegan) scroll.panGestureRecognizer.enabled = NO;
if(pinch.state == UIGestureRecognizerStateEnded) scroll.panGestureRecognizer.enabled = YES;

现在我的捏手动作生效了。
